FLUID-CLEANER.

Application filed December 12, 1907.

Specification of Letters Patent.

Patented April 6, 1909.

Serial No. 406,152.

To all whom it may concern:

Be it known that I, HENRY F. WEINLAND, a citizen of the United States,residing at $pringfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Boiler-Flue Cleaners, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to flue cleaners, and

- more particularly to a cleaning device in which the cleaner is drivenby a motor, carried through the tube with the cleaner.

The object of my invention is to provide an improved connection betweenthe motor and cleaner, whereby the power of the motor is transmitted tothe cleaner, with greater efficiency.

A further object is to so construct the motor in its relation to thecleaner, that undue strain and loss of power through friction areavoided, and the combined mechanism can be built in a more compact anddurable manner, to withstand the shocks and jars incident to thehammering and picking action of the cleaner.

While my invention is particularly adapted for the use of a water motor,it will be seen that in so far as the transmission of the power from themotor to the cleaner is concerned, air, steam or other suitable meansare used to actuate the motor.

With these and other objects in view, my invention consists of theconstructions and combinations hereinafter described and set forth inthe claims.

In the accompanying drawings, forming a part of this specification, andon which like reference letters indicate corresponding parts, Figure 1is a longitudinal sectional view of a motor with a cleaner carrying arm,shown partly in section, and a cleaner head thereon in elevation, theconstruction shown, embodying my invention. Fig. 2 is a turbine shaft orbody-carrier. Fig. 3 is a longitudinal sectional view taken at rightangles to Fig. 2. Fig. 4 is an outline of the cleaner carrying arm andthe pin on which it pivots. Fig. 5 is a driving shaft partly in section,taken at right angles to Fig. l. Fig. 6 is the pin on which said arm ispivoted, and Fig. 7 is a modification of the pivoted end of the arm.

The letter a, designates the outer case of a motor of suitable size, forpassage through a boiler tube, and having a forwardly ex tending reducedportion (1 Around said reduced portion on the shoulder a formed thereby,are a series of outlets a to pass the water from the turbine. A turbineshaft 6, has a recess 6 opening at its front end, and extendingrcarwardly, in which an arm 0 is pivoted on a pin 0 said recess and armbeing of such relative dimensions, that the free end of said arm willswing outwardly from the axis of the motor, giving the cleaner rZ, screwthreaded at (Z on the forward end of the shaft, sufiicient play to doits work.

A turbine wheel or runner c is mounted 011 the screw threaded portion 6of the shaft 7), the turbine wheel or runner having formed on itsperiphery, a series of inclined buckets seen in section at 0 theopenings through the buckets showing at 6 A feed headf is screwed intothe casing, to the screw threaded rear end I, of which casing anysuitable coupling may be attached to connect a supply hose. The motoractuating fluid is received from the supply hose into a chamber f andthence passes through the head to the buckets of the turbine wheel orrunner through ports f in the head f said ports being curved in awell-known manner, indicated by the dotted lines in Fig. 1. The head fis recessed at f" in its central portion, to receive the rear end 6 ofthe shaft Z). This construction forms a rear bearing for the motorshaft, against both longitudinal and lateral movements, and anintervening bushing 12* made of hardened material, is preferably used,so that when worn, it may be replaced. The forward end of the turbinewheel has a central recess to receive a hardened ring 6 which is screwedgradually enlarged from said center to each end thereof, as particularlyshown in Figs. 1, I and 5.

The pin 0 is held in an opening 6 extending transversely through theshaft 6, by the motor a and ring 6 mounted on the shaft over the ends ofsaid pin.

It will be seen that by pivoting the arm 0 on the pin as described, thearm is not only rotated and permitted to swing outwardly, from the axisof the motor, but further is given such flexibility, that it is alwaysfree to change direction in its forward movement, to follow through abent or curved tube, and I have found this additional universal freedomof action, gives greater eiiiciency to the cleaner in its hammer-ing andpicking action. The joint described is the form I prefer, but I do notlimit myself to this construction. Any coupling, whether universallyacting or otherwise, when pivoted within a motor, the wheel or runner ofwhich is protected by a casing and is adapted to rotate and swing thecleaner outwardly from the axis of the motor as described, I claim as myinvention. In Fig. 7, I have shown a modification in which an opening 0through the ball shaped end of the arm 0 is of uniform diameter,throughout its length to fit the pin 0 whereby the arm 0 is limited inits movement to swing outwardly from the axis of the motor in onedirection only.

It will be seen that by providing a recess in the motor to permit thefree end of the arm 0 to swing outwardly from the axis of the motor, Iam enabled to pivot it at its rear end within the body of the motor,thus transmitting the power at the pointof greatest eiiiciency andavoiding the strain, wear and loss of power by friction, that occurswhen the joint or coupling is made forward of the motor. The pivoting ofthe arm 0 in the rear of the front'bearing of the motor, and especiallybetween the two, when both front and rear bearings are provided isespecially desirable, giving strength, firmness and durability at thepoint of transmission of power.

I have shown a cleaner having a fixed head of special design (heretoforepatented by me) on the free end of the driving shaft, but I do not wantto be understood as limiting myself to this head. Any style of acleaner, whether with a fixed or rotating head, and whether having asingle arm or a plurality of swinging arms carrying cutters or cleanersof any kind, may be used by attaching the same to the forward or freeend of the arm 0 in any suitable manner.

The operation of my device is as follows: Having secured a cleaner tothe forward or free end of the driving shaft, and attached a supply hoseto the motor, the motor with its cleaner is inserted in and pushedthrough the tube to be cleaned, the actuating fluid driving the cleanerin the manner described to remove the scale from the tube.

Having thus described my invention, I claim:

1.. In a boiler tube cleaning device, a rotatable motor comprising arunner, a casing therefor adapted to protect the runner and stationaryin its relation thereto, front and rear bearings for the runner, acleaner carrying member pivoted within the motor between said bearingsand rotated thereby and adapted to swing outwardly from the axis of themotor, said cleaner carrying member being driven solely by the rotationof the runner, substantially as described.

3. In a boiler tube cleaning device, a rotatable motor comprising arunner, a driving shaft upon which said runner ismounted, said shafthaving a recess opening from its forward end extending rearwardly, acasing inclosing said runner having front and rear bearings to carry theshaft, said bearings being adapted to take the end thrust in bothdirections, a forwardly extending uninterrupted freely swinging armpivoted at its rear end within said recess between said bearings, anddriven by the rotation of the runner and a cleaner on the free end ofsaid arm, substantially as described.
